Failures of fly ash settling ponds, like the 2008 TVA spill, are extremely rare events, and in any case, only dry fly ash is used in concrete – not wet material in settling ponds. And lastly, the EPA has not indicated any desire to restrict fly ash use in concrete. 4) The use of fly ash and GGBF slag in concrete will reduce the amount of heat generated in the concrete mass that, in turn, will reduce thermal gradients and thermal stresses in concrete. 5) The resistance to freezing and thawing of concrete remains unaffected by the use of fly ash

Therefore the use of fly ash in structural concrete may bring a substantial saving in cement consumption and over all cost of concrete production. The fly ash is an industrial waste and great hazard for our environment. The designers of concrete structures therefore must incorporate the use of fly ash in their structural concrete. The results show that commercially available Australian fly ash and blast furnace slag materials are suitable for the manufacture of geopolymer concrete, using solid sodium metasilicate alkali activators.
